The built-in RC surge suppressor across the coil saves panel space and eliminates the separate suppressor selection step; just verify free-wheel diode polarity if you add external suppression downstream. The S0 footprint — 45 mm wide, 88 mm tall, 140 mm deep — fits standard panel layouts; side-by-side mounting is allowed with no derating gap. Screw-type terminals on the main circuit accept 2x (1 … 2.5 mm²) stranded or solid, up to 2x 10 mm² max.","metaTitle":"Siemens 3RT1024-3XG28-0MV0 SIRIUS S0 Power Contactor, 12.5 A","metaDescription":"Siemens 3RT1024-3XG28-0MV0 SIRIUS S0 power contactor, 12.5 A AC-4 at 400 V, screw terminals, built-in RC suppressor, 45 mm wide, current production.
